Question

Solve 1n 2+ 1n x=5

Answer 1

Isolate the variable by dividing each side by factors that don't contain the variable.

x =(5 / n) − n

The Answer To Solve n is in the image

Answer 2

x = 0.5
`e^(5)`

Explanation:

Using the rules of logarithms

log x + log y = log(xy)

`log_(b)` x = n ⇒ x =
`b^(n)`

given

ln 2 + ln x = 5, then

ln 2x = 5

Note ln =
`log_(e)`, thus

2x =
`e^(5)` ( divide both sides by 2 )

x =
`(1)/(2)`
`e^(5)` ≈ 74.21 ( to 2 dec. places )
